Those who grind their teeth or experience jaw pain often avoid hard foods like fresh fruits and vegetables and whole grains. A daily intake of fresh fruits and vegetables and whole grains are extremely important for good health and are major components of a healthy Mediterranean diet. People who suffer with TMJ pain and jaw problems gravitate to soft foods or an easy-to-chew diet—foods that require minimal chewing; and avoid raw, high-fiber foods that require a great deal of chewing.
